Performance of the Extended Ising Machine for the Quadratic Knapsack Problem
Haruka Akishima, Hirotaka Tamura, Kazue Kudo
The extended Ising machine (EIM) enhances conventional Ising models, which handle only binary quadratic forms by allowing constraints through real-valued dependent variables. We ad…
Generating gradients in the energy landscape using rectified linear type cost functions for efficiently solving 0/1 matrix factorization in Simulated Annealing
Makiko Konoshima, Hirotaka Tamura, Yoshiyuki Kabashima
The 0/1 matrix factorization defines matrix products using logical AND and OR as product-sum operators, revealing the factors influencing various decision processes. Instances and…
Characterization of Locality in Spin States and Forced Moves for Optimizations
Yoshiki Sato, Makiko Konoshima, Hirotaka Tamura +1
Ising formulations are widely utilized to solve combinatorial optimization problems, and a variety of quantum or semiconductor-based hardware has recently been made available. In c…
Efficient correlation-based discretization of continuous variables for annealing machines
Yuki Furue, Makiko Konoshima, Hirotaka Tamura +1
Annealing machines specialized for combinatorial optimization problems have been developed, and some companies offer services to use those machines. Such specialized machines can o…
